Definitions

  • the present invention relates to a well ring arrangement for a well cover or the like, for fixing a pipe element insertable in the well ring, said well ring having a shank portion, with an inner circumferential wall, defining an opening to receive an end portion of the pipe element.
  • the end of the pipe element is made with special cavities or holes cooperating with corresponding fixed projections on the inside or the outside of the shank portion of the well ring.
  • the projections snap into the cavities or holes as the pipe element is pushed onto or into the well ring.
  • the end of the pipe element has a annular groove which is to fit a complementary annular formation on the well ring shank.
  • a well lock wire element can be inserted into the annular groove formed between the shank and the pipe element to form an annular lock element holding the well ring and the pipe element together.
  • the present invention intends to remove the disadvantages of the known arrangements and suggests an arrangement which makes possible simple fixing of ordinary smooth-wall pipe elements in a well ring so that any require shortening of the pipe element can be done on site and the pipe then be simply fixed to the well ring.
  • At least one lock element is mounted in the cavity in the shank portion in such a manner that the lock element is movable from a first position, in which a grip edge portion, directed obliquely inwards in the insertion direction of the pipe element, of the lock element extends radially into the path of insertion of the pipe element to be fixed in the well ring, to a second position, in which the lock element, against the effect of a force, is held pressed against the cavity by the pipe element so that the lock element permits insertion of the end portion of the pipe element past the lock element, but prevents extraction of the pipe element from the well ring counter to said insertion direction, by pivoting the grip edge portion of the lock element to engagement with the outside of the pipe element when a separating force is applied between the well ring and the pipe element.
  • the present invention can be applied in an equivalent manner to a well ring to fix a pipe element pushed onto it, where the well ring has a shank portion with an outer circumferential wall over which an end portion of the pipe element is to be pushed.
  • the locking element is in this case mounted in a cavity in the shank portion in such a manner that the lock element can be moved from a first position, in which a grip edge portion of the lock element extending obliquely outwardly in the push-on direction of the pipe element extends radially outwards into the push-on path of the pipe element to be fixed to the well ring, to a second position in which the lock element is held, against the effect of a force, pressed in by the pipe element against the cavity, so that the lock element permits pushing on of the end portion of the pipe element past the lock element but prevents removal of the pipe element from the well ring counter to said push-on direction, by the grip edge portion of the lock element pivoting out into engagement with the inside of the pipe element when a separating
  • Each cavity has suitable opposite abutment surfaces to limit the pivotal movement of the grip edge portion of the lock element in the removal direction of the pipe element.
  • lock element is perferably biased to this first position with the aid of an elastic means, for example a compression spring, a rubber elastic element or the like, which acts directly on the lock element to facilitate engagement of its grip edge portion in the pipe wall, when a separating force is applied between the well ring and the pipe element.
  • an elastic means for example a compression spring, a rubber elastic element or the like, which acts directly on the lock element to facilitate engagement of its grip edge portion in the pipe wall, when a separating force is applied between the well ring and the pipe element.
  • At least two, but preferably three or more, lock elements are evenly spaced around the circumference of the well ring shank.
  • a well ring is generally designated 10, and is to be placed at ground level to support a well cover and a well pipe 12.
  • the ring 10 has an annular flange portion 14, the top 16 of which is to be at ground level, and a downwardly directed cylindrical shank portion 18.
  • An annular flange 20 extends from the inside of the shank portion 18, the top 21 thereof forming a seat for a well cover (not shown).
  • the underside 22 of the annular flange 20 forms an abutment for the pipe element 12, which is to be inserted and fixed in the well ring 10.
  • the well ring 10 is preferably made of metal, for example cast iron, while the pipe element 12 preferably consists of a lighter and softer material, such as plastic, for example polyethylene.
  • a pipelock which can automatically lock securely and strongly such a pipe to the well ring.
  • four such locking elements 26 and cavities 24 are symmetricaly arranged circumferentially, as shown in Fig. 3.
  • the cavity 24 has an inclined lower seat surface 28 on which the lock element 26 can rest in a passive state, as shown in Fig. 2a.
  • a resilient means 30, for example in the form of a rubber elastic body, is disposed to bias lock element 26 to the position shown in Fig. 2a.
  • the lock element 26 has a pointed grip edge portion 32 obliquely inwardly projecting into the path of insertion for the pipe element 22, and a rear edge 34, around which the lock element 26 can pivot at an interior corner 36 of the cavity 24, when the lock element 26 is acted on and by the end portion of the pipe element 12.
  • the pipe lock according the invention functions in the following manner:
  • the cavity 24 has an abutment surface 40 against which the rear portion of the lock element 26 can abut as shown in Fig. 2c.
  • the cavities 24, 24' in the embodiment shown are made as separate pockets for each lock element 26, it is also conceivable to make the cavities as a common circumferential groove in the shank portion of the well ring.
